Sonoma

Sonoma is a Webflow theme by Templates ($49). Tested on 2026-10-05 with Google Lighthouse via PageSpeed Insights on its own demo store, it scores 69 for mobile speed and 79 for desktop speed, 91/91 for SEO and 87/87 for accessibility (mobile/desktop, 0–100). Note: its demo home page is heavy — 6.5 MB — heavier than a typical store, so the speed score may understate the theme.
